so my lt1 on my 96 pontiac trans am went out i was thinking on doing the swap of a 5.3 or ls1 i just got my transmission rebuild 400 miles ago its an automatic 4l60e so would a 5.3 from a 2004 chevy silverado bolt into my 4l60 e and the ls1 to or no. i found a good deal on the 5.3 with every accessory and transmission and computer everything for the swap but idont know if i have to change something else is it worth doing the swap on either of them or should i just buy the lt1 thanks guys
